Aug 11, 2017 · The subject of this NASA/ESA Hubble Space Telescope image is a dwarf galaxy named NGC 5949. Thanks to its proximity to Earth — it sits at a distance of around 44 million light-years from us, placing it within the Milky Way’s cosmic neighborhood — NGC 5949 is a perfect target for astronomers to study dwarf galaxies.

NGC 6503 is a field [8] dwarf spiral galaxy [dubious – discuss] in the northern constellation of Draco. It was discovered by German astronomer Arthur von Auwers on July 22, 1854. [5] The galaxy has an angular size of 7.1′ × 2.4′ [7] and an apparent visual magnitude of 10.2. [5]

Dwarf galaxies like NGC 5264 typically possess around a billion stars. [3] One theory states that most galaxies, including dwarf galaxies, form in association with dark matter, [4] or from gas that contains metals. However, NASA 's Galaxy Evolution Explorer space probe identified new dwarf galaxies forming out of gases with low metallicity.

Hubble has also made detailed observations of the dwarf galaxy NGC 2366, which is home to a bright, star-forming nebula and is close enough for astronomers to discern its individual stars. While we see the stars because they shine brightly, galaxies are overwhelmingly made up of the empty space between them.

Apr 23, 2022 · Without obvious structure, but with visible signs of ongoing starbirth, NGC 5477 looks much like an archetypal dwarf irregular galaxy. The bright nebulae that extend across much of the galaxy are clouds of glowing hydrogen gas in which new stars are forming.

Aug 23, 2024 · Caldwell 17, also known as NGC 147, is a dwarf galaxy located roughly 2.5 million light-years from Earth. It is a member of the Local Group of galaxies, which is dominated by our Milky Way and the Andromeda galaxy.

With a mass of about a hundredth that of the Milky Way, NGC 5949 is a relatively bulky example of a dwarf galaxy. Its classification as a dwarf is due to its relatively small number of constituent stars, but the galaxy’s loosely-bound spiral arms also place it in the category of barred spirals.

May 12, 2011 · This is a full-field image of the nearby dwarf galaxy NGC 4214 taken with NASA's Hubble Space Telescope. Episodes of star formation are revealed as the galaxy continues to form clusters of new stars from its interstellar gas and dust.

Dec 2, 2024 · We report the discovery of three faint and ultrafaint dwarf galaxies—Sculptor A, Sculptor B, and Sculptor C—in the direction of NGC 300 (D = 2.0 Mpc), a Large Magellanic Cloud–mass galaxy.

May 11, 2022 · By studying NGC 247 in multiple forms of light (visible and infrared using Hubble, and X-rays using the Chandra X-ray Observatory), astronomers have found signs that the X-rays are coming from a disk around an intermediate-mass black hole.
